VRF虚拟路由转发实例说明

阅读更多关于 VRF虚拟路由转发实例说明

VRF实例说明 Virtual Routing Forwarding VPN 路由转发表，也称VPN-instance（VPN实例），是PE为直接相连的site建立并维护的一个专门实体，每个site在PE上都有自己的VPN-instance，每个VPN-instance包含到一个或多个与该PE直接相连的CE的路由和转发表，另外如果要实现同一VPN各个Site间的互通，该VPN-instance还就应该包含连接在其他PE上的发出该VPN的Site的路由信息。 MPLS VPN网络主要由CE、PE和P等3部分组成：CE(Customer Edge Router，用户网络边缘路由器）设备直接与服务提供商网络（图1中的MPLS骨干网络）相连，它“感知”不到VPN的存在；PE(Provider Edge Router，骨干网边缘路由器）设备与用户的CE直接相连，负责VPN业务接入，处理VPN-IPv4路由，是MPLS三层VPN的主要实现者：P(Provider Router，骨干网核心路由器）负责快速转发数据，不与CE直接相连。在整个MPLS VPN中，P、PE设备需要支持MPLS的基本功能，CE设备不必支持MPLS。 PE是MPLS VPN网络的关键设备，根据PE路由器是否参与客户的路由，MPLS VPN分成Layer3 MPLS VPN和Layer2 MPLS VPN

windows7系统链接vpn(使用预共享密钥的L2TP/IPsec)成功后,无法访问内网

我就奇怪了,远程办公遇到的问题怎么就是翻墙了？场景:公司远程办公开通了vpn,通过vpn访问公司内网问题 :windows7系统链接vpn(使用预共享密钥的L2TP/IPsec)成功后,无法访问内网问题解决:升级windows10系统可直接访问自己在win7解决的思路记录，本机测试均无效: 一、按照系统提示操作步骤链接，链接成功之后没有网络解决:在ipv4的远程网络关闭之后访问网络正常vpn也显示已连接,坑就在这里虽然都正常但访问不了内网；相当于ipv4的远程网络①关闭之后流量访问都是通过本机的外网走的 ②开启之后访问到了内网但内网没转发到外网导致访问不到外网也不是我所希望的样子； >>这样看来是否勾选并不能解决我当前问题，自己思考:勾选之后查看路由信息会发现所有远程网络(0.0.0.0)都会走默认网关(指的vpn的网关)并且优先级高于无线网络网关； >>这些勾选操作也是无作用的: >>这个勾选之后会导致本机无网络二、更改网络为工作公网三、固定ip地址解决:①无线网络ipv4进行本机ip固定;②vpn的ip固定；四、手动设置路由表解决:管理员身份打开cmd(普通身份打开无权限),手动设置内网ip指定走vpn,依然访问不了内网; 注：升级win10之后,打开cmd输入route print查看发现路由信息和win7连接vpn打开ipv4远程访问的路由一样的

Set a VPN connection programmatically on android 4.0

阅读更多关于 Set a VPN connection programmatically on android 4.0

问题 I'm working on programmatically setting a VPN connection on android devices. I was successfully able to do so for devices using OS 2.3.5 and before (I used reflection to get to the hidden classes). But with android 4.0 they got rid of the old classes and use the VPNService class instead. I figured the best place to start would be to use the ToyVPN example android provided, but I'm facing a lot of challenges with it. In the example code they only needed to send the server address:

问题 Currently I'm trying to figure out, how to add a VPN profile and connect to it from my universal app. I can connect to existing VPN connections with the Windows.Networking.Vpn namespace. I can also add a profile, but can not find a way to set all the required information (PSK for example). There is no documentation about this namespace in the MS docs. I also saw that there are two different profile namespaces available: VpnNativeProfile and VpnPlugInProfile . What is the difference between

问题 Ok, I am using a VPN on GoDaddy for webhosting. But on one of the websites that I am hosting, the email is handled on a separate VPN. So I have an A record for domain.com set to the GoDaddy VPN and an A record for mail.domain.com set to the IP of the other domain and several CNAMES pointed to that A record. It's all working beautifully except for one thing.... Email from other domains on the GoDaddy VPN cannot send to this domain. So myemail@mydomain.com cannot send to email@separateemailvpn
